Question after sending in the Adjustment of Status Paperwork

[Trymester3 6]

According to the USPS Tracking Info. the Chicago Lockbox received our package on June 21.

I am a US Citizen in New York City and she is a Japanese Citizen whom I married in April on a K-1 Visa. I am the sponsor, and my mother is another sponsor. I filled out a G-1145 E-Notification thing, but received no sorts of emails about anything. What was the point of the G-1145? When should I start getting impatient and think about making a call. What should I ask during the call?

I'm wondering when I will receive some sort of word (at least an RFE, which I don't want). I am a little bit nervous about my Affidavit of Support document. I read that I shouldn't worry about my credit or debt, but I am. My mother's credit and documents are all impressive though.
